Nonsymbiotic hemoglobins are ubiquitously expressed in plants and divided into two different classes based on gene expression pattern and oxygen-binding properties. Most of the published research has been on the function of class 1 hemoglobins. To investigate the role of class 2 hemoglobins, transgenic Arabidopsis (Arabidopsis thaliana) plants were generated overexpressing Arabidopsis hemoglobi...
Mir, P. S., Bittman, S., Hunt, D., Entz, T. and Yip, B. 2006. Lipid content and fatty acid composition of grasses sampled on different dates through the early part of the growing season. Can. J. Anim. Sci. 86: 279–290. In order to explore the value of herbage for the production of ruminant products with a high content of conjugated linoleic acid (CLA), a study was undertaken to determine the co...
In this study, the amounts of dry matter, moisture, crude ash, protein, fat and organic matter in T. boudieri were determined to be 89.75, 10.25, 7.80, 20.13, 3.45 and 81.95% of the dry weight, respectively. The contents of mineral were: macronutrients (mg/g, dry wt) K 63.8, Ca 0.27 and Na 0.2; micronutrients (mg/kg, dry wt) Fe 1455.0, Zn 42.5, Mn 15.8 and Cu 30.1. Toxic elements such as Pb, Ni...
BACKGROUND Trypanosoma cruzi is the causative agent of the life-threatening Chagas disease, in which increased platelet aggregation related to myocarditis is observed. Platelet-activating factor (PAF) is a potent intercellular lipid mediator and second messenger that exerts its activity through a PAF-specific receptor (PAFR). Previous data from our group suggested that T. cruzi synthesizes a ph...
The sarcoplasmic reticulum of skeletal muscle contains anionic phospholipids as well as the zwitterionic phosphatidylcholine and phosphatidylethanolamine. Here we study the effects of anionic phospholipids on the activity of the Ca2+-ATPase purified from the membrane. Reconstitution of the Ca2+-ATPase into dioleoylphosphatidylserine [di(C18:1)PS] or dioleoylphosphatidic acid [di(C18:1)PA] leads...
In this study, endogenous long chain ceramides were measured in 32 human head and neck squamous cell carcinoma (HNSCC) and 10 nonsquamous head and neck carcinoma tumor tissues, as compared with adjacent noncancerous tissues, by liquid chromatography/mass spectroscopy. Interestingly, only one specific ceramide, C(18:0)-ceramide, was selectively down-regulated in the majority of HNSCC tumor tissu...
